基于面向对象PETRI网的移动式Agent系统

 为了简化移动式Agent 的设计和实现,描述了以OOPN 为建模语言,建立移动式Agent 系统的基本原理。该系统提供了可视化系统建模、死锁检测和实际的系统运作功能。首先介绍OOPN 的基本概念和Agent 编程工具Aglets,在此基础上介绍如何通过OOPN 建模来生成移动式Agent 系统的具体实现机制,包括Agent 的远程创建和动态部署。最后通过生产者—消费者实例来说明整个系统的执行过程。

Modeling Mobile Agent with Object-Oriented PETRI Net

In order to simplify the design and implementation of mobile agents systems, a principle of building a mobile Agent system based on the Object Oriented PETRI Nets that are used as a system modeling language is described in the paper. The developing environment mentioned in the paper consists of visual system modeling, deadlock detecting, and actual system enacting tools. The basic concepts of OOPN and Aglets of Agent programming library are introduced first in this paper. Then, the implementing mechanism of generating a mobile Agent system based on OOPN is described, and algorithms for creating and deploying remote Agents are also introduced in the paper. Finally, an example on the producer and consumer problem is used to show the whole process of Agent system performing.
